Ye et al., Cell 2000
:
Thus, PIKE physiologically modulates the
activation by
NGF of nuclear
PI3K
Ye et al., Nature 2002
:
PIKE is a nuclear GTPase that activates nuclear PI(3)K activity, and mediates the physiological
activation by
nerve growth factor (NGF) of nuclear
PI(3)K activity
Nusser et al., J Biol Chem 2002
:
Taken together, these data indicate that
NGF mediated activation of TrkA receptor
stimulates PI3K , which in turn increases Rac1 activity to induce transient RhoA inactivation during the initial phase of neurite outgrowth
Halvorsen et al., Brain Res 2002
(MAP Kinase Signaling System...) :
Survival promoting MEK-ERK and PI3K pathways contribute to viability during MPP ( + ) exposure, both are
activated by
NGF , and loss of
PI3K mediated signaling and NF-kappa B-mediated transcription may commit cells irreversibly to apoptosis in this model
Salinas et al., J Biol Chem 2003
:
Inhibition of
PI3K prevented
NGF induction of HO-1 mRNA and protein and partially reversed its protective effect against 6-OHDA induced ROS release
Zhuang et al., J Neurosci 2004
(Hyperalgesia...) :
ERK
activation by capsaicin and
NGF was also blocked by
PI3K inhibitors
Ahn et al., EMBO J 2004
:
Here we show that nuclear
PI3K and its upstream regulator PIKE
mediate the antiapoptotic activity of
nerve growth factor (NGF) in the isolated nuclei
Park et al., J Biol Chem 2007
:
Specifically,
NGF enhanced TrkA phosphorylation,
PI3K activity, and Akt phosphorylation
Tucker et al., Cell Signal 2008
:
Inhibition of either Src or FAK activity attenuated both laminin and/or
NGF induced
PI 3-K/Akt and MEK/MAPK signalling pathways, as well as neurite growth
Kim et al., Neurochem Int 2010
:
Additionally, NPPB and SITS, another chloride channel blocker, suppressed
NGF induced TrkA phosphorylation and subsequent
PI3K/Akt phosphorylation and Rac1 activation in PC12 cells
Niewiadomska et al., Behav Brain Res 2011
(Alzheimer Disease) :
NGF released from target cells activates TrkA on axon terminals and
triggers activation of
PI3K/Akt , MEK/ERK, and PLC? ( phospholipase C ) signaling pathways
Ketschek et al., Communicative & integrative biology 2011
:
Thus,
NGF increases formation of axonal filopodia through localized
PI3K signaling that promotes the initiation of actin patch precursors to the formation of axonal filopodia
Liu et al., Exp Mol Med 2013
:
Similar to the changes in neurite outgrowth, the
PI3K/Akt activation by
NGF was potentiated by PIP5Ka KD, but was attenuated by the reintroduction of PIP5Ka
